the new function AddUserAgent adds the user agent to the stack
and formats it as per BIP 0014
e.g: "/btcwire:0.1.4/myclient:1.2.3(optional; comments)/"
the validation on UserAgent has been moved to a new function
validateUserAgent
- Coalesce the new bytes into the max message size constant to stay
consistent
- Correct optional relay tx field handling
- Rename the relay transactions field to DisableRelayTx so the zero value
of false has the correct default behavior
- Add tests for new bool fast paths in read/writeElement
- Stay consistent with version order in tests
- Add a single entry to TestVersionWire to test the new functionality
instead of adding a whole new TextVersionRelayTx function.
- Use BIP0037 in tests instead of hard coding 70001
- Nuke XXX that 70001 is different since this is handled now
- Fix and cleanup some comments
- Update test coverage report
Since fields of a version message after the AddrMe field are optional,
this commit adds a series of tests which ensure parsing version messages
which omit each of the optional fields works properly.
This commit modifies the MsgVersion.BtcDecode function to match the
behavior where fields after the first address field (AddrYou) are optional
and only read if the buffer contains remaining bytes.
Unfortunately this means the reader for MsgVersion.BtcDecode must be a
*bytes.Buffer or an error is returned. This is not an issue for the vast
majority of cases since all of the message reading code which is the main
way messages are read is already using a *bytes.Buffer, however, this
change might affect external callers if they are doing something special
with custom readers.
Fixes#14.
